Tom Lane's presentation on SERIALIZABLE etc?

Hi,

I remember there used to be somewhere a link to a talk Tom gave (on
OSCON 2001 maybe?) on transaction processing, SERIALIZABLE, SELECT FOR
UPDATE, etc.  I'm pretty sure it was linked to somewhere in the old
developers page, but I cannot find it in the new one or elsewhere.  I
searched the OSCON site but it isn't showing up either.

This one is not it:
http://www.postgresql.org/files/developer/transactions.pdf
Transaction Processing in PostgreSQL

Any clues?

Thanks,
